Patent
CA 2245817
An arrangement made up of an electrical circuit board (7) and an electrical pressure transducer (1) which has, in a housing (2), a pressure sensor onto which the pressure to be measured is transferred by means of a fluid through a channel (5) leading into the housing (2), and from which there proceed electrical lines which project out of the housing (2) as leads (4) and are connected to the circuit board (7). The channel (5) is shielded on the outer side of the housing (2) so that the flow resistance for fluid entering and leaving the channel (5) increases.
L'invention concerne un système comprenant une carte de circuits (7) électrique et un transducteur de pression (1) comportant un capteur de pression dans un boîtier (2), auquel est transmise la pression à mesurer à l'aide d'un fluide, à travers un canal (5) menant dans le boîtier (2) et d'où partent des lignes électriques qui font saillie du boîtier (2) sous forme de jambes (4) et qui sont connectées à la carte de circuits (7). Sur la face extérieure du boîtier (2), le canal (5) est blindé, de manière que la résistance hydraulique du fluide entrant dans le canal et celle du fluide qui le quitte soient renforcées.
